Possible applications For heating circuits with temperature differentials ≥20 °C / 68 °F The Vitocrossal 300 (lead boiler) and the next Vitorond (lag boiler) are operated via a Viessmann control system with outdoor reset logic, modulating boiler water temperature, and load-dependent sequential control – two-stage or modulating burners are controlled. Vitocrossal 300 is equipped with two return connections. The heating circuits with the higher return temperature are connected to the upper return connection, and those with lower return temperatures to the lower return connection. Please note: Connect at least 15% of the rated output to the lower return connection. Temperature sensor T1 senses the return temperature. The boiler control unit regulates the three-way mixing valve to ensure that the system never falls below the minimum return temperature. Due to the LON-BUS communication between controls, a boiler supply temperature is automatically set. This temperature is based on the highest required mixing valve circuit temperature plus adjustable differential.

Press 105 Function description – Vitotronic 100 Boiler temperature control Brief description The boiler water temperature is regulated by controlling a two stage or modulating burner. The set boiler water temperature set-point is controlled by Vitotronic 300-K, MW1S. Coding addresses which influence the boiler temperature control 02 to 06, 08 to 0b, 13 to 1C For a description, see the coding overview. Functions The boiler water temperature is monitored by three sensors separately, which are inserted into a multiple sensor well: Fixed high limit (STB) (liquid expansion) Adjustable high limit TR (liquid expansion) Boiler temperature sensor KTS (changes in resistance PT500) Control range limits top Fixed high limit STB 120 ˚C / 248 ˚F, adjustable to 110 or 100 ˚C/ 230 or 212 ˚F Thermostat TR 95 ˚C / 203 ˚F, adjustable to 87, 100 or 110 ˚C / 187, 212 or 230 ˚F. Electronic maximum limiter Setting range: 20 to 127 ˚C / 68 to 261 ˚F The maximum boiler water temperature limit can be adjusted via coding address 06. Lower control range limits In standard mode and when frost protection is active, the control unit regulates the boiler water temperature in accordance with the respective boiler. Control sequence Boiler heats up The burner shutdown point is determined by the switch-off differential (coding address 13). 5581 750 v1.3 Boiler goes cold (set value –2 K) The burner is activated if the oiler termperature is 2 ˚C / 3.6 ˚F below the calculated set point temperature. The burner may be delayed a few minutes depending on the connected auxilliary equipment and the fuel type. 106 Function description – Vitotronic 300-K, MW1S Cascade control unit Brief description The supply temperature is regulated by starting or stopping the burner or by starting/stopping individual burner stages. Depending on the type of control the boilers will be controlled to the set boiler water temperature determined by the cascade control (stand-alone type of control) or the cascade controls the boilers by pre-setting an individual boiler output (sequential control strategy). Subject to the system design, you may select between one gross calorific strategy and two net calorific strategies. The boiler sequence (see page 112) can be determined via coding 2 and the boiler sequence selection. Coding addresses which influence the cascade control 35 to 3F, 41 to 4A For a description, see the coding overview. Set supply temperature Upper control limit Electronic maximum system supply temperature limit. Setting range: 20 to 127 ˚C / 68 to 261 ˚F. The maximum supply temperature limit can be adjusted via coding address 37. This value must be set no higher than the lowest value of coding address 06 of all connected Vitotronic 100, GC1. Lower control range limit Electronic minimum system supply temperature limit Setting range: 20 to 127 ˚C / 68 to 261 ˚F. The minimum supply temperature limit can be adjusted via coding address 36. 5581 750 v1.3 The set supply temperature is determined from the supply temperature setpoint values of system circuit A1 and mixing valve circuits M2 and M3, the set supply temperature values of additional heating circuit loads (e.g. Vitotronic 200-H), the set DHW temperature and external demands (e.g. the set supply temperature required by coding address 9b or via the Input Module 0 to 10 V). 107 Function description – Vitotronic 300-K, MW1S Cascade control (cont.) Control sequence Stand-alone (Autonomous) type of control sequence Parallel boiler arrangement (coding 3b : 0 without supply temperature sensor or coding 3b : 1 with supply temperature sensor) With the stand-alone type of control in a parallel hydraulic boiler arrangement, the cascade control unit defaults the set boiler water temperature for all active boilers. Every Vitotronic 100, GC1 individually regulates the defaulted set temperature. Boilers arranged in series (coding 3b : 2 without supply temperature sensor or coding 3b : 3 with supply temperature sensor) With the stand-alone type of control in a series hydraulic boiler arrangement, the cascade control unit pre-sets the set boiler water temperature for all active boilers. Difference to parallel arrangement: When the lead boiler (condensing boiler) does not achieve the required boiler water temperature, it will only act to control the return temperature of all downstream boilers. In a series boiler arrangement, only the net calorific strategy 2 (see page 110) is useful. The conventional boiler is started late and is also shut down late. The control sequence is subject to the start-up and shutdown criteria set by the control strategy (coding address 3C): Gross calorific strategy Net calorific strategy 1 Net calorific strategy 2. Without supply temperature sensor: The control deviation is calculated from the set boiler water temperature and estimated average actual boiler water temperature of the active boiler to determine start-up and shutdown criteria. Only those boilers are taken into consideration whose isolation valve is not closed. 5581 750 v1.3 With supply temperature sensor: The control deviation is calculated from the set supply temperature and the actual supply temperature to determine the start-up and shutdown criteria. 108 Function description – Vitotronic 300-K, MW1S Cascade control (cont.) Sequential type of control sequence (coding 3b : 4) With the sequential type of control, the cascade control unit regulates to the required set supply temperature by pre-setting the output for each individual boiler. The lead boiler can be operated in modulating mode. All other boilers are operated in two stages via a defaulted output (incl. modulating burners). The control sequence is subject to the start-up and shutdown criteria set by the control strategy (coding address 3C): Gross calorific strategy Net calorific strategy 1 Net calorific strategy 2. With supply temperature sensor: The control deviation is calculated from the set supply temperature and the actual supply temperature to determine the start-up and shutdown criteria. Without supply temperature sensor: The control deviation is calculated from the set boiler water temperature and the estimated average actual boiler water temperature of the active boiler to determine the start-up and shutdown criteria. Only those boilers are taken into consideration whose isolation valve is not closed. Condensing strategy Advantages: Optimum utilization of the condensing effect (as many boilers active as possible) Long burner operating times Start-up criteria The boiler is started via an output statement (coding 3d : 1). An additional boiler will be started, when the currently required output can also be achieved by the currently active boiler plus the next boiler in the boiler sequence (see page 112). Shutdown criteria The boiler is shut down via a shutdown integral. The shutdown criteria is met when the shutdown integral exceeds a limit set via coding address 46, and the boiler started last will be shut down. 5581 750 v1.3 It is the aim of the gross calorific strategy to operate as many boilers as possible at the lowest output level. 109 Function description – Vitotronic 300-K, MW1S Cascade control (cont.) Net calorific strategy 1 Conventional boilers are preferably operated at their upper output range, to reliably prevent the formation of condensate due to low return temperatures. With net calorific strategy 1, an additional boiler will only be started if the maximum output of all currently active burners is insufficient to achieve the set supply temperature. A boiler will be shut down, when the remaining boiler(s) can achieve the required output on its/their own. Benefit: As few boilers as possible are active. Start-up criteria The boiler is started via a start-up integral. The start-up criteria is met when the start-up integral exceeds a limit set via coding address 45, and the next boiler in the sequence will be started (see page 112). Shutdown criteria The boiler is shut down via an output statement (coding 3d : 1). A boiler is shut down when the currently required output can be achieved without the boiler which was started last. With the net calorific strategy 2, an additional boiler will only be started if the maximum output of all currently active burners is insufficient to achieve the set supply temperature. A boiler will be shut down if the burner was returned to its minimum output because of a large negative control deviation, and the output is then still too high. Benefit: Long burner operating times Start-up criteria The boiler is started via a start-up integral. The start-up criteria is met when the start-up integral exceeds a limit set via coding address 45, and the next boiler in the sequence will be started (see page 112).

The ECO control becomes disabled, if the boiler is required to achieve the set supply temperature, when enabled boilers have failed. At least the lead boiler remains active if all boilers in a system are blocked by the ECO control. 5581 750 v1.3 The boiler sequence is determined by the boiler sequence selection and the following coding addresses (see also page 152): 38 Changing the lead boiler and the boiler sequence 38 : 1 Every 1st day of the month, the boiler with the burner which has operated for the shortest number of hours becomes lead boiler 38 : 2 After 200 to 20000 run hours, the boiler with the next higher number (coding address 07 of Vitotronic 100) becomes lead boiler 112 Function description – Vitotronic 300-K, MW1S Heating circuit control Brief description The control unit provides control circuits for one high temperature (boiler) circuit and two mixing valve circuits. The set supply temperature of every heating circuit results from the outdoor temperature, the set room temperature, the operating mode and the heating curve. The supply temperature of the system circuit corresponds to the common system supply temperature. The supply temperature of the mixing valve circuits is regulated by the stepped opening or closing of the mixing valves. Coding addresses which influence the heating circuit control 9F, A2 to A7, A9, C4 to C7, C8, F1, F2. For a description, see the coding overview. The mixing motor control changes the actuating and pause times subject to the control difference (control deviation). Functions Time program The control unit timer changes in accordance with the times programmed in the room heating and DHW heating program between the heating with normal room temperature and heating with reduced room temperature operating modes. Every operating mode has its own set level. Outdoor temperature A heating curve must be set up for matching the control unit to the building and the heating system. The heating curve characteristics determine the set boiler water temperature subject to outdoor temperature. An average outdoor temperature (dampened) is used for control purposes. This comprises the actual and the adjusted outdoor temperature. 5581 750 v1.3 The high temperature (boiler) circuit is subject to the boiler water temperature and its control range limits. The heating circuit pump is the controlling element. The mixing valve circuit supply temperature is recorded by the supply temperature sensor. 113 Function description – Vitotronic 300-K, MW1S Heating circuit control (cont.) Domestic hot water temperature With priority control: The set supply temperature will be set to 0 ˚C / 32 ˚F during DHW heating. The mixing valve closes, and the heating circuit pumps are switched OFF. Without priority control: The heating circuit control unit continues to operate with the same set value. With modulating DHW priority (only in conjunction with a mixing valve circuit): The heating circuit pump remains switched ON. The set supply temperature of the heating circuits will be reduced, for as long as the set boiler water temperature has not been reached during DHW tank heating. The set supply temperature is subject to the difference between the set and the actual boiler water temperature, the outdoor temperature, the heating curve slope and coding address A2. Room temperature in conjunction with remote control and room temperature input (observe coding address b0). Compared to the outdoor temperature, the room temperature has a greater influence on the common set supply temperature. This influence may be adjusted via coding address b2. In conjunction with the mixing valve circuit: For control differences (actual value deviation) above 2 ˚C / 3.6 ˚F room temperature, the influence can be increased again (via coding address b6, quick heat-up/quick setback). Quick heat-up: The set room temperature must be raised by a minimum of 2 ˚C / 3.6 ˚F by: Pressing party button Changing from heating with reduced temperature to heating with normal temperature Start-up optimisation Quick heat-up will stop when the set room temperature has been reached. Heating circuit pump logic (economy circuit) The heating circuit pump is switched OFF (set supply temperature set to 0 ˚C/ 32 ˚F), when the outdoor temperature exceeds the value selected via coding address A5. 5581 750 v1.3 Quick setback: The set room temperature must be reduced by a minimum of 2 ˚C / 3.6 ˚F by: Pressing economy button Changing from room heating with normal temperature to heating with reduced temperature Shutdown optimisation Quick setback will stop when the set room temperature has been reached. 114 Function description – Vitotronic 300-K, MW1S Heating circuit control (cont.) Extended economy circuit The heating circuit pump is switched OFF, and the set supply temperature is set to 0 ˚C / 32 ˚F, if the outdoor temperature exceeds the value selected via coding address A6 the set room temperature is reduced via coding address A9 in conjunction with the mixing valve circuit: the mixing valve has been closed for 12 minutes (mixing economy function, coding address A7) Slab curing function (only in conjunction with a mixing valve circuit) Please note: Four different temperature profiles can be selected for drying the slab. These profiles are activated via coding address F1. You can influence the control characteristics of the mixing valve via coding address C4. Central operation Central operation for all downstream heating circuits can be programmed via coding address 7A. The heating and holiday program then applies to all heating circuits in the system. The programming unit of the other heating circuits displays central control when the heating program and holiday program buttons are activated. Any set holiday programs in the heating circuit programming units will be deleted. Party and economy buttons on all control units are without effect. Frost protection When the outdoor temperature falls below +1 ˚C / 34 ˚F, a supply temperature of at least 10 ˚C / 50 ˚F will be safeguarded. For changes see coding address A3, variable frost limit. 5581 750 v1.3 When the slab curing function is activated, the heating circuit pump of the mixing valve circuit is switched ON, and the supply temperature will be held at the selected profile. After completion (30 days), the mixing valve circuit will be regulated automatically via the set parameters. System dynamics – mixing valve circuit (only in conjunction with a mixing valve circuit) 115 Function description – Vitotronic 300-K, MW1S Heating circuit control (cont.) The differential temperature is that minimum temperature differential by which the common supply temperature should be higher than the currently required supply temperature of the mixing valve circuit. System with only one mixing valve circuit: The common set supply temperature will be automatically held 8 ˚C / 15 ˚F above the set supply temperature of the mixing valve circuits. System with high temperature (boiler) circuits and mixing valve circuits: The common set supply temperature operates in accordance with its own heating curve. The differential temperature of 8 K towards the set supply temperature of the mixing valve circuits is set up at the factory. Upper control limit Electronic maximum limit Setting range: 1 to 127 ˚C / 34 to 261 ˚F Changes via coding address C6. 110 230 Supply temperature °C / °F +8K Supply temperature control Differential temperature: The differential temperature may be adjusted via coding address 9F; factory supplied setting 8 ˚C / 15 ˚F . 87 189 8K +20/ 68 -20/-4 Outdoor temperature in °C / °F A Max. common supply temperature B Slope = 1.8 high temperature (boiler) circuit C Slope = 1.2 mixing valve circuit D Common supply temperature (at a differential temperature = 8 ˚C/ 15˚F ) E Minimum common supply temperature Lower control range limit Electronic minimum limit Setting range: 1 to 127 ˚C / 34 to 261 ˚F Changes via coding address C5 (only effective in standard mode) Please note: The maximum limit is no replacement for the underfloor heating system temperature limiter. Mixing valve circuit The mixing valve motor will not be activated within the neutral zone (±1 ˚C / 2 ˚F). 116 Supply temperature falls (set value –1 ˚C / -2 ˚F) The mixing valve motor receives the open signal. The signal duration lengthens with an increasing control differential. The duration of pauses reduces with an increasing control differential. Supply temperature rises (set value +1 ˚C / 2 ˚F) The mixing valve motor receives the close signal. The signal duration lengthens with an increasing control differential. The duration of pauses reduces with an increasing control differential. 5581 750 v1.3 Control sequence Function description – Vitotronic 300-K, MW1S DHW tank temperature control Brief description The DHW tank control logic is a set-point control. It is the result of starting and stopping the DHW pump. The switching differential is ±2.5 ˚C / 4.5 ˚F. During DHW tank heating, a constant boiler supply temperature will be set (20 ˚C / 36 ˚F higher than the set DHW tank temperature, adjustable via coding address 60) and space heating is switched OFF (optional DHW tank priority). Coding addresses which influence the DHW tank control 54 to 75, 7F, A2. For a description, see the coding overview. Time program An automatic program or an individual time program may be selected for DHW heating and the control of the DHW recirculation pump. Compared with the space heating circuit’s heat-up phase, DHW heating in automatic mode starts 30 minutes earlier. The individual time program enables up to four switching periods per day to be set via the time switch to control the DHW heating/heating and the DHW recirculation pump. Any DHW tank heating sequence will be completed, independent of the time program. In conjunction with coding address 7F 7F : 1 Detached house: Automatic mode For systems with two or three space heating circuits, the heating times for the first of the existing heating circuits will be applied. Individual time program The switching times for DHW heating and the DHW recirculation pump have the same effect on all heating circuits. 7F : 0 Apartment building: Automatic mode For systems with two or three heating circuits, the heating times for the respective heating circuit will be applied. Individual time program The switching times for DHW heating can be adjusted separately for each heating circuit. DHW priority With DHW priority (coding A2 : 2): The set supply temperature will be set to 0 ˚C / 32 ˚F while the DHW tank is being heated. The mixing valve closes, and the heating circuit pumps are switched OFF. With DHW priority: The heating circuit control unit continues to operate with the same set value. Set DHW temperature The set DHW temperature can be adjusted between 10 and 60 ˚C / 50 and 140 ˚F. The set range can be expanded to 95 ˚C / 203 ˚F via coding address 56. You can select the set DHW temperature at the programming unit of the control and at every Vitotrol 300 remote control unit (if installed). You can determine the allocation to individual heating circuits via coding address 66. Auxiliary circuits The DHW heating can be disabled or enabled by changing over the heating program. Functions 5581 750 v1.3 Frost protection The DHW tank will be heated to 20 ˚C/ 68 ˚F, if the DHW temperature falls below 5 ˚C / 41 ˚F. Auxiliary functions – DHW heating This function is activated by providing a second set DHW temperature via coding address 58 and activating the 4th DHW phase for DHW heating. DHW recirculation pump It delivers hot water to the draw-off points at adjustable times. Up to four control periods can be set at the timer. System with DHW tank heating system The above functions also apply in conjunction with calorifiers. Set the following codings 4C : 1, 4E : 1, 55 : 3. For a description, see the coding overview. Systems with Vitosolic A third DHW temperature set-point can be programmed via coding address 67. Reloading suppression will be active below the set temperature. The DHW tank is heated only by the solar heating system. 117 Function description – Vitotronic 300-K, MW1S DHW tank temperature control (cont.) Control sequence Pump delay The DHW pump continuous operation (coding 62 : 10) after the DHW tank heating, until – the difference between the boiler water and the DHW temperature is less than 7 ˚C / 13 ˚F or – the common supply temperature is achieved based on outdoor reset calculations or – the actual temperature is 5 ˚C / 9 ˚F higher than the set DHW temperature or – the maximum time delay (adjustable via coding address 62) has been reached. Without the pump time-delay for DHW tank heating (coding 62 : 0) Coding 55 : 0: DHW heating The DHW tank goes cold (set value –2.5 ˚C / 4.5 ˚F, adjustable via coding address 59) The common supply temperature is adjusted 20 ˚C / 36 ˚F higher than the set DHW (adjustable via coding address 60). With adaptive DHW tank heating, the speed of the temperature rise during DHW heating is taken into account. Also taken into account is the question of whether the boiler will be required to supply heat after the DHW tank has been heated or whether residual boiler heat should be transferred to the DHW tank. Accordingly, the control unit determines the burner and DHW recirculation pump shutdown point to prevent the set DHW temperature being substantially exceeded after the DHW tank has been heated. Coding 55 : 2: DHW tank temperature control with 2 DHW tank temperature sensors The 1st DHW tank temperature sensor enables the DHW pump, and is evaluated for stop conditions during the pump run-on time. The 2nd DHW tank temperature sensor (inside the cold water inlet) is designed to prematurely start DHW tank heating when large quantities of DHW are drawn off as well as to prematurely stop DHW tank heating if no DHW is drawn. Coding 55 : 3: DHW tank control – DHW heating (for DHW heating systems only) The DHW tank goes cold (set value –2.5 ˚C / -4.5 ˚F, adjustable via coding address 59), The common set supply temperature is adjusted 20 ˚C / 36 ˚F higher than the set DHW temperature (adjustable via coding address 60). The primary DHW pump is switched ON. The three-way mixing valve opens and then regulates to the defaulted set value. The DHW pump cycles (short term ON and OFF) until the set supply temperature has been reached, then it runs constantly. If, during DHW tank heating, the actual value stays below the required set supply temperature, then the DHW pump will temporarily cycle again. The DHW tank is hot (1st DHW tank temperature sensor: Actual value ≥ set value and 2nd DHW tank temperature sensor: Actual value > set value –1.5 ˚C / -2.7 ˚F) the common set supply temperature is returned to the weathercompensated value; the DHW pump – is immediately switched OFF, if the three-way mixing valve is open or – is switched OFF after run-on time adjustable via coding 62. 5581 750 v1.3 The DHW tank is hot (set value +2.5 ˚C / 4.5 ˚F) The common set supply temperature is returned to the weathercompensated value.
